Defense shines again for Dallas

ARLINGTON – While the offense will have plenty of red zone work to do when camp resumes Saturday in Oxnard, Calif., the defense already seems ready for the regular season as the Cowboys head into halftime with a 3-0 lead over the Raiders.

Pro Bowl cornerback Terence Newman and Co. haven’t given up any points in the preseason while displaying the same aggressiveness that helped them finish last season as one of the top defenses in the league.

Cowboys backup nose tackle Junior Siavii, perhaps feeling some heat from rookie Josh Brent, sacked Jason Campbell for a 9-yard loss in the first quarter. Later in the first half, Saivii emerged from a pile without his helmet and sporting a bloody cut on his forehead after stopping running back Rock Cartwright for a 2-yard gain.
